5.7 Connecting TH320
Requirement
If you use stranded wire used, you need a ferrule.
Note the maximum permissible core cross-section (Page 140).
Procedure
1. Connect the input or inputs to terminals 3 to 6.
2-wire, 3-wire or 4-wire RTD or
linear resistance
I1: Input 1
TC (internal CJC or
external 2-wire or 3-wire CJC)
Voltage input
(unipolar and bipolar)
3-wire or 4-wire potentiometer
2. Connect the supply voltage to the terminals 1 (+) and 2 (-).
Take the polarity into account. The device has reverse polarity protection.
For devices with HART communication, connect a ≥ 250 Ω resistor.
